MC78L05ACPG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92-3

MC78L05ACPG from onsemi, in a TO-92-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Output power_out Regulated 5.0 V output of the MC78L05ACPG, suitable for supplying up to 100 mA as stated for the MC78L00A Series.
2 Ground power_in Common ground that the datasheet requires to be shared between the input and output voltages.
3 Input power_in Unregulated input that must remain typically 2.0 V above the output even at the low point of the input ripple, with an absolute maximum input of 30 V for the 5.0 V version.
